(1) Beneficial ownership is determined in accordance with the Rule of the SEC
and generally includes voting or investment power with respect to
securities. Except as otherwise indicated by footnote, and subject to
community property laws where applicable, the persons named in the table
have sole voting and investment power with respect to all shares on Common
Stock shown as beneficially owned by them. Numbers reflect ownership prior
to the date of this Supplement.
(2) Includes Conversion Shares based on a conversion price of $30.904 per share
and a cash payment in lieu of any fractional interest.
Because the Selling Securityholders may offer all or some of the Notes that
they hold and/or Conversion Shares pursuant to the offering contemplated by
this Prospectus, and because there are currently no agreements,
arrangements or understandings with respect to the sale of any of the Notes
or Conversion Shares by the Selling Securityholders, no estimate can be
given as to the principal amount of Notes or Conversion of Shares that will
be held by the Selling Securityholders after completion of this offering.
